'To au whom it may concern:

. Beit known that I, FRANK O. ELLIs, a citizen of the United States, residing in the city and count of'Philadelphia, State of Penn- Sylvania, ave invented a new and useful Fountain-Pen, of which the following .is a

specification.

My invention relates to'improvements' in v av fountain-pen in which provision is made for supplying thel barrel or reservoir thereof with ink through the pen-holding end thereof, thus avoiding a separate filler and the requirement of uncovering either end of said barrel or reservoir for such-purposes, While also simplifying and vastly improving an ar-A ticle of the class, the means employed and the operation thereof being hereinafter described and the novel features thereof pointthe previous 1 figures. Fig. 5 represents a portion of Fig. 4 with certain parts thereof` in different positions.

Sirnilllagletters oreference indicate correspon :parts in t e figures.

Referring to the drawings, A designates the barrelor reservoir of a fountain-pen; B, thepen-holding4 member thereof, the same being removably held in said barrel, and C the covering-ca. thereof, said member having therein the mk-supplying duct D and the port E, the latter forminga communicationv etween said duct andthe interior of the reservoir A. 'Within saidreservoir is the piston F, Whose stem 'G is tubular 'and has an internally-threaded collar G forV the engagement of the screw-threaded rod H, which stem asses freely through an opening in the flat e A on the end of the reservoir and has on its outer terminal the head J, which resting' flat against said `flange Vserves to close said opening and prevent in said reservoir from escaping at saidend,

as niost plainly shown in Fig. 2.` Y

When the reservoir is to be supplied with ink, the head J is rotated, whereby the rod H is unscrewed, thus extending the stem G as shownin-Fig.3.` Thepen-nibisnow laced in ink and the piston F is operated in e resspecification of Letters Patent.

J, which may be grasped, ynow serving as a knob or handle, it being evident that ink by suction isA drawn through the d uct- D and passing through the port E enters the reservoir, thus supplying the latter. of-I the rod H are continuous, preferably from end to end, so that said rod may remain.

connected with the tubular stem G Whether said rod is screwed into the stem to a folded condition, as in Fig. 2, or screwed out therefrom to operative position, as in Fig. 3, without disconnecting the telescopic connection of the piston and preventing play of the inner member or rod H and rattling of the same. vOwing to the collar G, which is secured within the bore of the stem G at oneA end thereof, I avoid the threadin of said bore, the short thread of said col ar bein ysuflicient for the connection of the rod with said stem in the i'n-and-out position of said rod. The rod H is now screwed into'the stem G and the head J reaches the adjacent flange A of the reservoir, the parts resuming their normal positions, as shown -in Fig. 2. The o en end of the cap is then fitted on the head andabuts against the ad'acent terminal of the reservoir, thusrm y sustaining said cap and forming a continuity of the lat-.

ter, as shown in Fig. 1, and as the pen-nib is now supplied withink the writing may be proceeded with as usual in an article of the kind. In Figs. 4 and 5 I show the'rod H passing through an opening in a rounded flange K on the reservoir and also show the pen-holdin member B as separate from the reservoir an adapted to be screwed into the latter, Whilev in Fi 1 and 2`the reservoir and pen-holdin mem er are found in one piece orV integra without, however, producing different re- 1 sults.

- Various changes may be made in the details of construction shown withoutdeparting' from the eneral spirit of my invention,

and I do not, t erefore, desire t'o be limited in each case to the same.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is- 1. In a dfevice o f the class described, the 1 combination with a pen-barrel having an end wall rovided with an opening, of a pistonrod t eaded throughout substantially its entire length and movable freely through said opening, and a piston threaded onto the rod within the barrel. l

2. a device of the class described, the

The threads combination with a pen-barrel havin an end Wall rovided .with 'an opening, o a -rod threa ed throu h substantially its entire length and mova ing, a head provided on the outer end o ,the rodfand a iston threaded onto thelatter .Within the arrel.

3. In a fountain-pen, a reservoir, a piston, a telescopic stem connected with said piston, 1o said-stem consisting of a threaded member an exterior tubular section,' and a threade collar secured Within saidsection, and having said threaded member engage solely --therewith, and a head :with a flat inner face on the outer end of said threaded member -on'the exterior of said reservoir, said head being adapted to abut against the adjacent 'end of the latter.

4. In a fountain-pen, aireservoir having zo an inturned flange at-an end thereof, a piston, a telescopic stem connected with the latter and formed of a tubular section which freely 'occupies said lan e and a threaded member "f which engages Wit the interior of said tubuz5lar section, alhead which is secured tothe outer end of said mem-ber and ada tedto -abut against'said flange formin a s oulder therewith, and a 4covermg-cap. a a ted to be fitted on saidhead and'engage sai shoulder.

le freely through said: o r1-` 5. In a fountain-pen, a reservoir, a iston, a telescopic stem connected with sai reservoir, said stem consistin of a threaded member, an exterior tubu ar section,and a threaded collar secured within said section,

and. having said threaded member engage solely therewith, and a head on the outer end of said threaded member on the exterior of'said tubular section, said reservoir havin an inturned flan e against which said hea is *adapted to a ut and form a shoulder therewith and a covering-cap ada ted to be fittedon'said head and engage sai shoulder.

6. In a fountain-pen, a reservoir, a piston, a telescopic stem for said piston formed of a tubular section having an unthreaded bore and an internally-threaded collar secure within said bore, a threaded member en aging said collar, a head on the outer en of sald memberand exterior of the adjacent end of said reservoir, the same being adapted to abut against said end of the reservoir and a covering-cap adapted to be fitted on said head.
